ing of the surface of the embossing die.

Our invention consists in the parts and in the details of construction andarrangement of parts as will hereinafter be more fully described and claimed.

In the drawings: Figure 1 isa sectional diagrammatic illustration of part of an embossing press with our invention applied thereto; Fig. 2 is an enlarged cross section, on the line ma: of Figs. 4 and 5, of a device embodying our invention; Fig. 3 is a further enlargedcross section of the upper part of the blade and of the pressure bar, with the web passing between the blade and pressure bar, and also illustrating how the ink is removed from the web, the thickness of the layer of ink, however, being exaggerated; Fig. 4' is a plan view of the device; and Fig. 5 is a rear elevation of the same;

The press which we have chosen for illustrating the use of our invention has the embossing die 1 reciprocated by a lever 2 through the medium of links 3 and 4, back toward the fountain'5 and forward to the front of the press, not shown, where the impression is made. The fountain 5 has the roller 6 taking up ink 7 from the fountain, with a. doctor roller -8 bearin thereon; and a distributing roller 9, suita ly carried on an arm 10, takes the ink from the roll 6' and distributes it over the die 1 when the die is back near the fountain. The ink is thus s read over the entire surface of the die an down in the de ressions formed by the engravin on the ie, such as the depressions 11 tierein, but only the ink in the depressions is to be transferred to the work, as is well known in the art of embossing and printing with one im ression. Therefore, a means is provided or wiping all of the ink from the die except that in the depressions 11. On this press, a pad 12 with a tightly stretched surface of suitable fabric 13, such as felt, has a web of paper 14 drawn under it, so that, as the die 1 passes under the pad 12, the upper surface of the die and the lower surface of the web 14 are very tightly pressed together and all of the ink on the plane surface of the die is wiped off onto the web 1 1. This web of paper 14 is supplied from a roll 15 near the top of the press, which roll is roperly retarded by a strap 16 suspended rom an arm 17 and held against the roll by the weight 18. The web passes forward and down over suitably arranged rollers to the pad 12 and back under the pad to a roll 19, upon which the paper is wound. The roll 19 is intermittently turned by suitable mechanism, which need not be described, but which comprises the rod 20, making connection with a moving part of the press; and in this manner a new length of the web of paper is brought under the pad 12 at each reciprocation of the die 1, and each new length thus receives a quantity of ink from the plane surface of the die. The web wound on the roll 19 with these quantities of ink thereon becomes waste paper, and of course, whatever ink remains on the web when it is rolled up on the roll 19 is wasted.

The above details of the parts are described to facilitate the understanding of our invention, but it will be understood that any other press with a web wiping the surface ink from the die or form may be pro vided with our invention.

As here shown in connection with the press above described, brackets 21 and 22 are clamped to a cross bar or strut 23 which this press has at the rear, and these brackets have a blade 24: rigidly fixed to them by screws 25. A. pressure bar 26 is hinged to the bracket 21 to drop down over and along the upper edge of the blade 24, and the other bracket 22 has a latch 27 which will hold the pressure bar 26 down along said edge of the blade 24. By means of this hinged mounting the pressure bar 26 may be raised and the web 14 where it passes from the pad 1.2 up to the roll 20 may be brought under the pressure bar 26 and thus press down against the upper edge of the blade 24, so that the blade may scrape. off a large portion of the ink that the web 14 has wiped from the die 1 and is carrying upward toward the roll 20. This ink, thus scraped from the .web 14, runs down the forward or inner side of theblade 24, where it is caught by a chute 28 that slants rearwardly and downwardly, so that this ink is thus. delivered back to the fountain 5 and thus adapted to be used instead of wasted. It is of' course highly desirable to scrape off as large a proportion of this ink from the web as ispossible; but it is also necessary to avoid scraping off any of the fiber of the paper of which the web 14 is composed; because such fiber, mingling with this ink and passing back to the fountain will soon adulterate the ink, so that the impressions obtained will be inferior, and may even show the fibers thus present in the ink. Another precaution that is necessary is to carry the web 14 across the edge of the blade 24 withouttearing or cutting the web. To avoid these difficulties we provide a flat thin flexible pressure-regulatin strip 29 held up against the flat lower sife of the pressure bar 26 by screws 29' passing up through the strip at its ends, into the pressure bar, and provide a plurality of adjusting screws 30 passing down through thepressure bar at intervals therealong and bearing against the upper side of the strip. Under this pressure-regulating strip 29 a pad-31 of suitable fabric, such as felt, is interposed; and the lower corners 32 of thepressure bar 26 are rounded, and this pad 31 is stretched from one side of the pressure bar down under the rounded corners 32 and under the lower side of the strip 29 and up to the other side of the fpressure bar, being held to the sides -0 the pressure bar by plates 33 with screws 34 passing through them and through the pad 31 into the sides of the'pressure bar. As shown in 'Fi 2 we preferably place an additional strlp 35 under the strip 29, somewhat forward of the edge of the blade 24, and held also by the screws 29. This presses the material of the pad 31 and of the web 14 very slightly downward, so that the 'web must travel upward very slightly to meet the edge of the blade, thereby better facilitating the scraping of the ink from the web.

With the device constructed as just described, and with the pressureregulating screws 30 at close intervals along the pressure bar 26, and with the pressure-regulat ing strip 29 moderatelv flexible, each short interval of length of the edge of the blade 24 may-{have the web pressed against it with exactlfithe right pressure to scrape most of the in from the paper and yet not disturb the fiber of the paper. The pad 31, interposed between the pressure-regulating strip 29 and the edge of the blade, in conjunction with the rounded corners of the pressure bar 26 and with the chamfered edges 29 of the adjusting strip 29, allows the web to pass under and around the pressure bar with the pressure so distributed upon it that it is not cut or torn. The edge of the blade 24 is preferably made somewhat dull, so as not to' cut the surface of the web. The blade may be narrowed as indicated by ther dotted line A in Fig. 5, if the ink is of such nature that it does not run freely off the wider blade.

The chute has sides 36 with hooks 37 which slip ov'er screws 38 passing into the inner sides of the brackets 21 and 22, so that this chute 28 may be readilyremoved from the device to allow convenient access to the mechanism of the fountain and inkdistributing means.

After the ink has been distributed on the die and then wiped off and carried up by the web and then recovered by our device, it is generally dried out somewhat and becomes of somewhat thicker consistency. This ink, passing back to the fountain and mingling with the fresh ink therein, will,

after some operation'of the machine, generally increase the thickness of consistency of the ink in the fountain to an objectionable extent. To compensate for this, we may provide a supply of a suitable thinning liquid, such as turpentine, supplied to the ink in minute quantities. Thus, each of the brackets 21 and 22 may be provided with rearwardly projected lugs 39 at their lower ends, and a bar 40 may be fixed to these lugs 39 by screws 41, which bar 40 may support cups 42 at intervals the'realong, with stems 43 extending through the bar 40 to deliver the thinnin liquid to the chute 28, there to mingle wit the ink that has run down from the blade 24. The cup 42 may have a cut-off 44 to regulate the volume of the liquid delivered, which will generally be set so that the liquid drips very slowly from the cup into the chute, since only a very small quantity of the thinning liquid is generally required to maintain the proper consistency of the ink in the fountain with this recovered ink being delivered back thereto.

-As here shown, the brackets 21 and 22 have rearwardly projected pedestals 45 and caps 46 that embrace the bar 23 before alluded 'to, and the ca 46 being held to the pedestal by screws 4 which, when drawn up, clamp the entire device very rigidly to this bar '23. The device may be clamped to the bar 23 at any suitable angle to receive the web around the under side of the pressure ban, 26 in such a manner as to avoid ciitting tendency of the blade 24. Thus, as shown in Fig. 1, the device is tilted forward somewhat, for this reason.

Other means may be employed for attach-. ing the device to the machine parts, espetherefore we do not Wish to be understood as being limited to the details of construction and arrangement herein set forth as an 7 example, but
